How to Fix CVE-2026-102676
To remediate this vulnerability, upgrade all affected Electron dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
npm install electron@41.10.6npm install electron@42.9.2npm install electron@43.4.1npm install electron@44.0.0-beta.5Run the following command in your project directory to verify that all resolved dependencies use the patched release:
npm ls electronHow to Check if You Are Affected
To determine whether your Node.js application is affected by CVE-2026-102676, inspect your project dependencies using npm:
npm ls electronAnalyze the terminal output to locate any version of Electron in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 41.10.6), your application is affected.
Note: The npm ls electron command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-269: Improper Privilege Management, where the product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.

Apps that do not use `<webview>`, or that keep the embedder sandboxed, are not affected.\n\n### Workarounds\n\nRemove `nodeIntegrationInWorker` from the guest preferences in a `will-attach-webview` handler, or do not enable the `<webview>` tag when loading untrusted content.\n\n### Fixed Versions\n\n* `44.0.0-beta.5`\n* `43.4.1`\n* `42.9.2`\n* `41.10.6`\n\n### For more information\n\nIf you have any questions or comments about this advisory, email us at [security@electronjs.org](mailto:security@electronjs.org)",
